In September, Reclamation’s maintenance crew at Flaming Gorge Dam had the rare task of disassembling one of three power generators at the facility, for a scheduled ‘rewedge.’ For many on the crew, this was a first experience—the last rewedge occurring more than 20-years ago. “This is a unique experience for us to see a unit all torn apart like this … to see the internal workings of everything.” said apprentice plant mechanic, Eric Johnson. “It’s a big process for us here at the plant. All trades are involved in the effort.”
The Flaming GorgePowerplant produces approximately 500,000,000 kilowatt hours of energy annually which is enough to serve about 50,000 households. Take a sneak peek inside the facility and follow the path of water from reservoir to turbine in this brief overview.

There are more than 3,000 rivers in Vietnam, provide resources to feed millions of people and bring livelihoods to hundreds of communities. When the rivers change, fishermen and farmers are the first to be affected.
By September 2013, more than 800 hydropower projects were planned, more than 250 hydropower projects operated, and more than 200 hydropower projects under construction. By 2013, due to only 21 hydropower projects in 12 provinces, more than 300,000 people were displaced and resettled. How are their lives now…?

Hydroelectric is the use of moving water to turn turbines that generate electricity, usually through the building of dams or pump stations on rivers.
And hydroelectricity is the king of renewable energy, making up 70% of the renewable energy produced around the world. And for good reason.
They’re kind-of the perfect energy source. It’s stable, base-load energy that’s flexible. If you need more electricity, just release more water into the turbines.
They’re cheap to run and maintain once they’re built and they’re 95% efficient at generating energy, compared to 33% for coal and 15% for solar.
And of course they create no pollutants, consume no fuel, and the water never stops flowing.
The Three Gorges Dam in China is actually the largest energy plant of any kind in the world and generates just under a hundred terawatt hours per year all by itself.
So, hydro is kinda perfect. The problem is, it’s location-specific.
If you don’t live by a large river, you’re not going to be able to use it. Luckily, most cities were built near rivers, but not all rivers are large and powerful enough to make enough difference to justify the cost of building them.
Which is also a problem. While they produce free energy for decades and even centuries after they’re built, hydroelectric dams are huge engineering projects that cost tons of money up front.
(By the way, the whole ‘expensive at first but then free for decades’ thing is a common theme amongst renewable energies)
They also create reservoirs and lakes that flood a lot of land whose landowners may not want to give up.
There are some concerns about the disruption of fish habitats, but… that’s not at the top if my list of concerns.
So each hydroelectric plant is a birds nest of legal and construction challenges to overcome but even so, the number of hydropower plants are expected to double by 2050.
Another base load energy source is geothermal energy.
Geothermal uses the heat from natural geologic hotspots to turn turbines that generate electricity.
Iceland and the Philippines are major producers of geothermal power, which can be used in huge commercial plants to power entire cities or just pump the heat directly into homes for heating.
It’s a consistent flow of energy so it never runs out, but the efficiency isn’t great. Only an average of 12% efficiency.
Which really just means it will take longer for the investment to build it to pay off because once it’s turned on, it’s just free energy basically. And the efficiency is getting better, with newer plants getting over 20%.
https://www.geothermal-energy.org/pdf/IGAstandard/NZGW/2012/46654final00097.pdf
Even in Iceland, which is covered in hotspots and has a very progressive attitude toward clean energy, it only accounts for 30% of their energy production.
So it’s not likely to become a major source of energy worldwide
And as if all that wasn’t enough of a bummer, it also turns out that geothermal can produce greenhouse gasses.
Geologic hotspots churn up all kinds of stuff from inside the Earth, stuff like sulfur dioxide and silica emissions, and heavy metals like mercury, arsenic and boron.
These can get in the reservoirs and eventually the water supply.
Oh, and by the way, one of the methods they use to open up geothermal wells is hydraulic fracking. Yeah. That hydraulic fracking.
Let’s drill down and inject extremely high pressure water and other chemicals… Right over a volcano.
What could go wrong?
Earthquakes. That’s what.
Just like fracking for natural gas has caused earthquakes in Oklahoma...
(zoom in)
Earthquakes. In Oklahoma.
A geothermal well that was drilled in Switzerland set off an earthquake that measured a 3.4 on the Richter scale.
(pained)
Geothermal… Why do you hurt me so?
I used to think geothermal was really cool. Used to.
So am I wrong about this? Do you have experience using geothermal, or working in hydro plants? Are my numbers garbage? Let me know in the comments
The next video in this series will focus on biomass energy and harnessing the motion of the ocean to make power.

The Three Gorges Dam in China is actually the largest energy plant of any kind in the world and generates just under a hundred terawatt hours per year all by itself.
So, hydro is kinda perfect. The problem is, it’s location-specific.
If you don’t live by a large river, you’re not going to be able to use it. Luckily, most cities were built near rivers, but not all rivers are large and powerful enough to make enough difference to justify the cost of building them.
Which is also a problem. While they produce free energy for decades and even centuries after they’re built, hydroelectric dams are huge engineering projects that cost tons of money up front.
(By the way, the whole ‘expensive at first but then free for decades’ thing is a common theme amongst renewable energies)
They also create reservoirs and lakes that flood a lot of land whose landowners may not want to give up.
There are some concerns about the disruption of fish habitats, but… that’s not at the top if my list of concerns.
So each hydroelectric plant is a birds nest of legal and construction challenges to overcome but even so, the number of hydropower plants are expected to double by 2050.
Another base load energy source is geothermal energy.
Geothermal uses the heat from natural geologic hotspots to turn turbines that generate electricity.
Iceland and the Philippines are major producers of geothermal power, which can be used in huge commercial plants to power entire cities or just pump the heat directly into homes for heating.
It’s a consistent flow of energy so it never runs out, but the efficiency isn’t great. Only an average of 12% efficiency.
Which really just means it will take longer for the investment to build it to pay off because once it’s turned on, it’s just free energy basically. And the efficiency is getting better, with newer plants getting over 20%.
https://www.geothermal-energy.org/pdf/IGAstandard/NZGW/2012/46654final00097.pdf
Even in Iceland, which is covered in hotspots and has a very progressive attitude toward clean energy, it only accounts for 30% of their energy production.
So it’s not likely to become a major source of energy worldwide
And as if all that wasn’t enough of a bummer, it also turns out that geothermal can produce greenhouse gasses.
Geologic hotspots churn up all kinds of stuff from inside the Earth, stuff like sulfur dioxide and silica emissions, and heavy metals like mercury, arsenic and boron.
These can get in the reservoirs and eventually the water supply.
Oh, and by the way, one of the methods they use to open up geothermal wells is hydraulic fracking. Yeah. That hydraulic fracking.
Let’s drill down and inject extremely high pressure water and other chemicals… Right over a volcano.
What could go wrong?
Earthquakes. That’s what.
Just like fracking for natural gas has caused earthquakes in Oklahoma...
(zoom in)
Earthquakes. In Oklahoma.
A geothermal well that was drilled in Switzerland set off an earthquake that measured a 3.4 on the Richter scale.
(pained)
Geothermal… Why do you hurt me so?
I used to think geothermal was really cool. Used to.
So am I wrong about this? Do you have experience using geothermal, or working in hydro plants? Are my numbers garbage? Let me know in the comments
The next video in this series will focus on biomass energy and harnessing the motion of the ocean to make power.

In this first part of a 3-part series, I examine hydropower and geothermal energy as options to power a clean energy grid.

World Energy Congress | The Role of Multipurpose Hydropower in a Water-Stressed World

Hydropower provides over 16% of global electricity production and the sector has the potential to double its capacity to 2,000GW by 2050. Emerging markets are increasingly recognising the benefits that multipurpose hydropower can bring in a water-stressed world; in addition to delivering clean low-cost electricity and enhancing energy security, hydropower can provide water services, encourage regional cooperation and be a pillar of economic development. However, increasing competition for water usage, a higher frequency of droughts and flooding over the past decades, as well as the potential effects of new developments on local environments and communities are challenges that have to be carefully managed.
Questions
How can the sector best manage the increasing competition for water?

Colorado Experience: Hydro Power

In 1891, due to a lack of timber fuel and the challenge of steep mountain passes, all mining operations in Telluride were in danger of being shut down. Cue L.L. Nunn. This Colorado pioneer financed Ames Hydroelectric Generating Plant, the first in the world to generate alternating current electric power for industrial application. Thanks to this historic milestone, Telluride’s Gold King Mine remained open and hydroelectric plants soon popped up across the United States and the world.

Can hydropower be environmentally sustainable?

The Nature Conservancy's Jeff Opperman asks the question "Can hydropower be environmentally sustainable?" Hydropower development has potential risks and rewards, and many upcoming projects are proposed in regions with high convergence of both biodiversity and ecosystem services. Opperman encourages conservation scientists to focus on the strategic deployment of dams rather than opposing them across the board.

1:02:38 Panel Debate
1:56:40 Q&A
2:04:40 Concluding remarks
Moderated by:
Jean-Michel Glachant | Florence School of RegulationPresentation by:
Vincent Rious | Florence School of Regulation and Microeconomix
Panellists :
Otto Pirker | Eurelectric and Verbund
Roberto Potì | Assoelettrica, Utilitalia and Eurelectric BoardFrancescoSalerno | Cleary Gottlieb Steen & HamiltonOliverKock | DG Ener, European Commission
The newly published FSR report on ‘Regimes for granting the right to use hydropower in Europe’ will be presented by the authors and debated with a high-level panel with representatives of EU institutions, National Regulatory Authorities, industry and academia, as well as with any other relevant stakeholder attending this event. The Luncheon debate will also be live-streamed.
Further information on the discussion theme
Over the last decade, the EU Commission launched several investigations in different countries (e. g. France, Spain, Italy, and Portugal) on the compatibility of hydropower rights with European laws and regulations. Nevertheless, a few regimes (i.e. Austria or Sweden), despite not being grounded on competitive process, were excluded from the inquiry.
Although hydro is key to EU energy transition, two complications can be identified:
-Member States have totally different and non-harmonised frameworks,
-The EU Commission has three diverging voices on this topic: competition, environment, and “only last” energy.
The report aims to provide a balanced benchmark of hydropower concession regimes, by analysing and comparing 14 countries (Austria, Bulgaria, Finland, France, Germany, Great-Britain, Greece, Italy, Norway, Poland, Portugal, Spain, Sweden and Switzerland) and regions when appropriate (cantons in Switzerland or Lands/States in Germany).

National Geographic Megastructures
Megastructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia.
Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products.
Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases (such as the Akashi-Kaikyo Bridge and Petronas Towers) this involved the development of new materials or products that are now in general use within the construction industry.
Megastructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first (such as Dubai's Palm Islands). This type of project is known as a megaproject.
The series follows similar subjects as the History Channel's Modern Marvels and Discovery Channel's Extreme Engineering, covering areas of architecture, transport, construction and manufacturing.

Off-Grid Hydro Power: Too Much Power!

This off-grid hydro power system has a major problem; too much power. Jeff has stumbled upon a small clan of off-grid homeschoolers and discovers that their power system is a major source of angst.
Their stream engine produces around 1200-1300 Watts continuously and their load controller must get rid of any excess power by dumping the power into a hot water tank. Image the struggle to use copious amounts of hot water!

Hydropower at Flaming Gorge Dam

In September, Reclamation’s maintenance crew at Flaming Gorge Dam had the rare task of disassembling one of three power generators at the facility, for a scheduled ‘rewedge.’ For many on the crew, this was a first experience—the last rewedge occurring more than 20-years ago. “This is a unique experience for us to see a unit all torn apart like this … to see the internal workings of everything.” said apprentice plant mechanic, Eric Johnson. “It’s a big process for us here at the plant. All trades are involved in the effort.”
The Flaming GorgePowerplant produces approximately 500,000,000 kilowatt hours of energy annually which is enough to serve about 50,000 households. Take a sneak peek inside the facility and follow the path of water from reservoir to turbine in this brief overview.

Lives behind hydropower dams

There are more than 3,000 rivers in Vietnam, provide resources to feed millions of people and bring livelihoods to hundreds of communities. When the rivers change, fishermen and farmers are the first to be affected.
By September 2013, more than 800 hydropower projects were planned, more than 250 hydropower projects operated, and more than 200 hydropower projects under construction. By 2013, due to only 21 hydropower projects in 12 provinces, more than 300,000 people were displaced and resettled. How are their lives now…?
This film included videos from field trips (2013-2015) to resettlement and downstream areas of Sesan 3, PleiKrong, Yaly, Serepok, and Ho Ho hydropower dams by PanNature.

They also create reservoirs and lakes that flood a lot of land whose landowners may not want to give up.
There are some concerns about the disruption of fish habitats, but… that’s not at the top if my list of concerns.
So each hydroelectric plant is a birds nest of legal and construction challenges to overcome but even so, the number of hydropower plants are expected to double by 2050.
Another base load energy source is geothermal energy.
Geothermal uses the heat from natural geologic hotspots to turn turbines that generate electricity.
Iceland and the Philippines are major producers of geothermal power, which can be used in huge commercial plants to power entire cities or just pump the heat directly into homes for heating.
It’s a consistent flow of energy so it never runs out, but the efficiency isn’t great. Only an average of 12% efficiency.
Which really just means it will take longer for the investment to build it to pay off because once it’s turned on, it’s just free energy basically. And the efficiency is getting better, with newer plants getting over 20%.
https://www.geothermal-energy.org/pdf/IGAstandard/NZGW/2012/46654final00097.pdf
Even in Iceland, which is covered in hotspots and has a very progressive attitude toward clean energy, it only accounts for 30% of their energy production.
So it’s not likely to become a major source of energy worldwide
And as if all that wasn’t enough of a bummer, it also turns out that geothermal can produce greenhouse gasses.
Geologic hotspots churn up all kinds of stuff from inside the Earth, stuff like sulfur dioxide and silica emissions, and heavy metals like mercury, arsenic and boron.
These can get in the reservoirs and eventually the water supply.
Oh, and by the way, one of the methods they use to open up geothermal wells is hydraulic fracking. Yeah. That hydraulic fracking.
Let’s drill down and inject extremely high pressure water and other chemicals… Right over a volcano.
What could go wrong?
Earthquakes. That’s what.
Just like fracking for natural gas has caused earthquakes in Oklahoma...
(zoom in)
Earthquakes. In Oklahoma.
A geothermal well that was drilled in Switzerland set off an earthquake that measured a 3.4 on the Richter scale.
(pained)
Geothermal… Why do you hurt me so?
I used to think geothermal was really cool. Used to.
So am I wrong about this? Do you have experience using geothermal, or working in hydro plants? Are my numbers garbage? Let me know in the comments
The next video in this series will focus on biomass energy and harnessing the motion of the ocean to make power.

FSR debate on hydropower rights

0:07:23 Introducing the FSRReport | Vincent Rious
0:27:59 Q&A
1:02:38 Panel Debate
1:56:40 Q&A
2:04:40 Concluding remarks
Moderated by:
Jean-Michel Glachant | Florence School of RegulationPresentation by:
Vincent Rious | Florence School of Regulation and Microeconomix
Panellists :
Otto Pirker | Eurelectric and Verbund
Roberto Potì | Assoelettrica, Utilitalia and Eurelectric BoardFrancescoSalerno | Cleary Gottlieb Steen & HamiltonOliverKock | DG Ener, European Commission
The newly published FSR report on ‘Regimes for granting the right to use hydropower in Europe’ will be presented by the authors and debated with a high-level panel with representatives of EU institutions, National Regulatory Authorities, industry and academia, as well as with any other relevant stakeholder attending this event. The Luncheon debate will also be live-streamed.
Further information on the discussion theme
Over the last decade, the EU Commission launched several investigations in different countries (e. g. France, Spain, Italy, and Portugal) on the compatibility of hydropower rights with European laws and regulations. Nevertheless, a few regimes (i.e. Austria or Sweden), despite not being grounded on competitive process, were excluded from the inquiry.
Although hydro is key to EU energy transition, two complications can be identified:
-Member States have totally different and non-harmonised frameworks,
-The EU Commission has three diverging voices on this topic: competition, environment, and “only last” energy.
The report aims to provide a balanced benchmark of hydropower concession regimes, by analysing and comparing 14 countries (Austria, Bulgaria, Finland, France, Germany, Great-Britain, Greece, Italy, Norway, Poland, Portugal, Spain, Sweden and Switzerland) and regions when appropriate (cantons in Switzerland or Lands/States in Germany).

National Geographic Megastructures
Megastructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia.
Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products.
Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases (such as the Akashi-Kaikyo Bridge and Petronas Towers) this involved the development of new materials or products that are now in general use within the construction industry.
Megastructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first (such as Dubai's Palm Islands). This type of project is known as a megaproject.
The series follows similar subjects as the History Channel's Modern Marvels and Discovery Channel's Extreme Engineering, covering areas of architecture, transport, construction and manufacturing.
National Geographic (formerly National Geographic Channel and also commercially abbreviated and trademarked as Nat Geo) is the American digital cable and satellite television channel that is owned by National Geographic Partners, majority-owned by 21st Century Fox with the remainder owned by the National Geographic Society.

Colorado Experience: Hydro Power

In 1891, due to a lack of timber fuel and the challenge of steep mountain passes, all mining operations in Telluride were in danger of being shut down. Cue L.L. Nunn. This Colorado pioneer financed Ames Hydroelectric Generating Plant, the first in the world to generate alternating current electric power for industrial application. Thanks to this historic milestone, Telluride’s Gold King Mine remained open and hydroelectric plants soon popped up across the United States and the world.

Can hydropower be environmentally sustainable?

The Nature Conservancy's Jeff Opperman asks the question "Can hydropower be environmentally sustainable?" Hydropower development has potential risks and rewards, and many upcoming projects are proposed in regions with high convergence of both biodiversity and ecosystem services. Opperman encourages conservation scientists to focus on the strategic deployment of dams rather than opposing them across the board.
WWF is always looking for new ways to advance the scientific foundation that supports our global conservation work. Learn more about the Fuller Symposium and the Kathryn Fuller Science for Nature Fund: http://www.worldwildlife.org/science/fellowships/fuller/fuller-symposium-2011.html
